Hey guys. Linux noob here. Question: I am reading the Linux Command Line and just encountered expansion commands. I understand that the $ prefix to let's say USER is variable, but I'm not exactly understanding their purpose. Anyone have a handy explanation?

If I understand your question correctly, this can be used to define variables for script.
eg:# export UnixGuy="hi" # echo $UnixGuy
